How this service works
Live status checks for AI agents. Is this product still available or sold out (Shopify, eBay)? Is this job posting still open (Greenhouse, Lever, Ashby, Workday)? Real-time answer with evidence. $0.01 per check via x402 or Stripe MPP.
Output
Returns a status classification of 'live', 'closed', or 'unknown' for the given URL, along with the page title and a set of signals detected on the page such as presence of an apply form, sold-out indicators, or a 404 HTTP response — giving the agent enough context to decide whether to proceed with further processing.
Example use cases
Pre-scrape job listing validation
“I'm about to pull data from this job posting — can you check if https://careers.acme.com/jobs/1234 is still open or if it's been filled and taken down?”
E-commerce sold-out detection
“Before adding this product to our aggregator, check if https://shop.example.com/products/blue-sneakers-sz10 is still live and available, or if it's showing a sold-out page.”
Dead link filtering before bulk processing
“We have this URL from our job board crawl — can you quickly verify whether https://startup.io/jobs/growth-marketer is returning a real live page or a 404 before we queue it for processing?”
Technical details
Endpoint
POSThttps://livecheck.fly.dev/v1/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap pre-flight check on a specific job or product page URL before investing time or cost in scraping or processing it. Prefer it over a general scraper when you only need live/closed/unknown status and basic signals rather than full page content. Ideal for filtering dead links, detecting sold-out products, or confirming job postings are still open in a pipeline before downstream enrichment.
Side effects
- URL is behind a login/paywall, returning unknown status
- Cloudflare or bot-protection blocks the fetch, yielding unknown
- Malformed or non-absolute URL returns a validation error
- Network timeout on slow or unresponsive target server
- Search-results or index URLs passed instead of specific item pages may yield misleading signals
